I would still fish the wire through the walls. I've used some of the surface mount wire hiders. I guess it works ok, as long as you don't plan on removing it until the next wall repair paint job comes alone. It does make repairing the wall necessary when you remove them. I probably should of scraped them off with a knife. Instead, I just grabbed and ripped. Layers of paint and portions of drywall came out with it. Oops. Maybe I am Cat the Ripper.
